The first one is just something I saw out my window when the sun reflected off the circular object.

Ya gotta love Geri's colors (click to enlarge).

The last one I took this afternoon from my living room as two fighter jets leave the area after flying over Yankee Stadium on Opening Day. They were probably still over the Bronx, at least 10 miles away. The foliage is in Fort Lee/Cliffside Park.

The first four pictures were taken right by the river, the fifth on Main, and the sixth on a very uneven-looking Anderson St, which appears to have a downhill component and too many wires and streetlights (one is on) above it........and the yellow lines don't come close to lining up before and after the tracks.

No function at all. It is what you might call "architectural license" where the architect tried to replicate some design feature he saw elsewhere and was trying to carry through the entire Church design. Basically it is an abstract of a doorway on the bottom and two window openings above.Now look at photo #2. The doorway there is of similar scale to the doorway in photo #1 as are the windows.

I was thinking about bells too, but it seemed odd to me that bells would be placed in the back of a church.

Holy Trinity Church celebrates its 150th anniversary this year, but the current building is not the original. Information provided by Editor in this thread: - http://www.hackensacknow.org/index.php?topic=530.0 - indicates that the current building was dedicated in 1932.
